. with coin controlled means for closing the circuit of a motor thatactuates an appara-. tus, and for subsequently opening said circuitautomaticall upon completion of each operation of sai apparatus; and toso construct said switch that upon a succession of operations of saidcoin controlled means, said motor circuit will be closed and theapparatus maintained active throughout a series of operationscorresponding in number withthe operations of said coin controlled meansbefore the motor circuit is automatically opened.

The accompanying drawings are illustrative embodiments of the inventionand do not include an instrument or device actuated by the motor that iscontrolled by the switch, as such instrument or device may be of anycharacter capable of being controlled by the present invention, or for apurpose other than that of a musical instrument. Also, the coincontrolled means illustrated in the drawings for operating the switchmay be of any suitable character, as the particular construction thereofis immaterial to the present invention, or a substitute means for saidcoin controlled apparatus may be employed instead for controlling saidswitch, and therefore, the use of the invention is extensive beyond thatherein specifically set forth.

In the drawings,

Fig. 1 is a front elevation of an electrically operated switch in whichthe invention is embodied, and includes in diagram form parts associatedtherewith;

Fig. 2 is a side elevation projected from Fig. 1, some parts being insection, or cut away, and other parts being omitted; and

Fig. 3 is 'a rear view of the accumulator wheel, the spring contactingmembers and the segmental contact plate therefor.

The illustrative embodiment of the invention consists of a housing orbase 1 having mounted thereon a stationary stud 2 upon which isrotatively mounted a wheel 3 having upon its perimeter an annular seriesof radially projecting pointed teeth 4 equally spaced and in closeformation.

Upon the back of the wheel 3 is concentrically positioned a segmentalcontact plate 5, there being a void 6 between the opposing ends of theplate.

An insulator 7 on the base has a pair of spring contact members 8 and 9,both of which have electrical contacting engagement with the plate 5constantly except upon registration with the void 6.

A stationary stud 10 extends from the base 1 and aflords support for ajigger 11, that has made therein an opening 12 through which the shank13 of the stud 10 loosely extends. The opening 12 is wider at its lowerend than at its to and is so shaped and proportioned as to adinit ofvertical and lateral play of the jigger upon the shank of the stud. Thejigger has connected at its lower end a retracting spring 14 that isconnected to a stationary pin 15 that projects from the base 1, whichspring tends to hold the jigger normally centered in vertical positionupon the stud 10. The jigger has an upwardly extending actuating finger16, pointed at its top, and also oppositely extending lateral wings 17and 18, each being provided with an armature, 19 and 20 respectively,consisting of an iron plate. Above the armatures, on the base 1, aresecured a corresponding pair of electro-magnets 21 and 22, radiallydisposed with respect to the stud 10, or at an upwardly inclined anglethat is divergentwith respect to the vertical center of the jigger. The

lower end of each magnet is spaced from the corresponding armature onthe jigger when said jigger is in normal position so as to permitmovement of the jigger when one or the other 1 of the magnets isenergized and the corresponding armature ismagnetically attractedthereby.

The electro-magnet 21 is connected in circuit by conductors 23 and 24with one or more coin controlled devices 25, and a source of electricalenergy, such, for exam le, as a transformer 26. The coin controlledevices may be of any suitable structure provided with a switch 27arranged so as to operate upon the reception of a coin in thecommutrolled device and momentarily close the circuit of theelectromagnet 21.

The electro-magnet 22 is connected in circuit by means of conductors 28and 29 with a suitable source of electrical ener y, such as said.transformer 26, said-circuit eing controlled by anautomatically'operated switch 30 which is related to the motor-drivenmusical instrument or other appliance (not shown) in anysuitable manner,whereby the switch 30 is momentarily closed upon the 2.completion of thecycle of operation of said instrument or device, as b a reciprocatingmember 31 activated there y upon completion of its operation.

The electrical motor 32 which is o eratively related with saidinstrument or evice is connected in circuit by means of conductors 33and 34, with a suitable source of electrical energy, such as a generator35, said circuit being controlled through the medium of the contactmembers 8 and 9 and'the contact plate 5, which have connected relationwith the conductor 34.

The transformer 26 may, if so desired, be suitably connected with agenerator so as to be energized thereby, or may receive current from anyother suitable, source.

In the o eration of the. invention, uponj closing oft e switch 27 by theinsertion of a. coin 1n the corresponding coin controlled device, theelectro-magnet 21 is momentarily energized by current supplied from thetransformer 26 through the conductors 23 and 24, whereupon, the armature19 is magnetically attached and drawn toward the magnet, which causesthe jigger 11 to move upwardly and over toward the magnet, and thefinger 16 is thereby raised into contact with the adjacent tooth 4: andexerts lateral pressure against the tooth toward said magnet, causingthe wheel 3 to turn in the corresponding direction to a limited extent.When the wheel is thus turned, the contact-plate 5 is likewise moved, sothat its void'6 is moved out of regis- .tration with the contactingmember, whereupon electrical contact is made between the member 9 andthe contact plate 5 so that the circuit between the generator 35 and themotor 32 is closed, thereby causing operation of the instrument or otherdevice. Upon re-opening of the switch 27, the electro-magnet 21 becomesde-energized and the jigger, under the influence of the spring '14:,becomes again centered upon the stud 10, in its neutral position. Uponcompletion of the operation of the device that directions selectively bythe jigger an is driven by the motor 32 and cons uent closing of theswitch 30 through the m ium of the reciprocating member 31, which isautomatically operated by said device, the electro-magnet 22 isenergized, whereupon, the armature 20 is magnetically attracted anddrawn toward said magnet, whichcauses the jigger 11 to move upwardly andovertoward said magnet, and the finger 16 is thereb raised into contactwith the adjacent toot 4 and exerts lateral pressure against said toothtoward said magnet, causing the wheel 3 to turn in the correspondingdirection to a limited extent. When the wheel is thus turned, thecontact plate 5 is likewise moved so that its void 6 is moved intoregistration a as would be occasioned by repeated operations of thecoincontrolled devices, the jigger 11 will be operated by the magnet 21 acorresponding number oftimes, and the accumulator wheel 3 will beprogressed tooth by tooth to a corresponding extent, and the void in thecontact plate will be moved to a point more or less remote fromregistration with the motor circuit will remain closed and operation ofthe instrument or device Wlll con-- tinue through successive cyclesuntil the wheel contacting member 9. In this manner, the

3 is returned to its normal or open position v by the successiveoperation of the jigger 0ccasioned by ,the' magnet 22 which occurrespectively upon the closing of the switch 30 at the completion'of eachcycle of operation of the instrument. If a number of coins are insertedin successive order in the coin controlled devices, the instrument willbe caused to operate continuously throughout a number of its cyclescorresponding with the number of coins so inserted, and willautomatically cease operation upon completion of the last of saidcycles. The wheel 3 is cumulative with respect to the extent of itsaction when the magnet-21 is repeatedly energized, and retrieved to itsnormal position when the magnet 22'is subsequently energized acorresponding number of times. Thus, the switch wheel is rotativelymoved in opposite variable extent dependent upon activity of the opposedmagnets.

What I claim is 1. A cumulator switch for controlling the energizingcircuit of an electrically operated device, consisting of'a pair ofopposed magnets provided each with a separate switch controlledenergizing cir uit therefor; a movably mounted jigger having asingle'finger and provided with means normally holding it in neutralposition and arranged to be actuated in opposite directions respectivelyby said magnets; a cumulator operatively related with said jigger so asto be moved se- 5 lectively in opposite directions by said fingeraccordingly as said magnets are at different times energized; andcontacting means related with said cumulator for controlling the circuitof said device. 2, A cumulator switch for controlling an electriccircuit, consisting of a cumulator having thereon a contact plate; amovably mounted jigger having a single fin er'and provided with meanstendin to hold it in neutral position, arranged to e activated inopposite directions by said finger and to impart movement to saidcumulator accordmgly; electro-magnetic means related with said jigger soas to actuate it selectively in oposite directions; and contacting memrs reating said contact-plate with a circuit to be controlled therebi.
